Definition

Glaucoma
describes a group of eye diseases that cause damage to the optic nerve. This degenerative eye disease is one of the leading causes of chronic blindness in the United States.

Angle-closure glaucoma is a condition in which the iris in the eye shifts and blocks the exit passageway of
the fluid
in the front compartment of the eye. This fluid blockage causes a rapid build-up of pressure in the eye.

Slit-lamp examination—the use of a low-power microscope combined with a high-intensity light source, allows a narrow beam that can be focused to examine the front of the eye

Gonioscopy—to examine the outflow channels of the angle

Treatment

Angle-closure glaucoma requires emergency medical treatment to preserve vision. See an ophthalmologist right away if you have any signs or symptoms of an angle-closure glaucoma attack. Treatment options include:

Medications—Eye drops, pills, and sometimes even IV drugs are given to reduce intraocular pressure.

Surgery—Surgery may be used to stop or prevent an attack of angle-closure glaucoma. This is usually done by laser.

Prevention

Angle-closure glaucoma cannot be prevented. However, it is important to get regular eye exams to screen for glaucoma and other conditions that can affect your vision. Talk to your doctor about how often your eyes should be examined.
